Cell adhesion and migration play essential roles in tissue development and maintenance, and abnormal cell migration is involved in life-threatening diseases, including vascular disease, tumor formation, and metastasis. The advances in hydrogel-based 3D cell culture development facilitated the investigation of cell motility behavior, including cell-cell and cell-matrix adhesion and cell migration in a microenvironment more related to in vivo situations. Establishing advanced methods for these in vitro studies is thus necessary. Photo-sensitive proteins show advantages in remote and non-invasive regulation of hydrogels’ properties, and thus are of great potential in regulating 3D cultured cells’ behavior. In the presented study, we engineered photocleavable protein(PhoCl)-decorated hydrogels to regulate cell adhesion and migration of MDA-MB-231. The integrin-binding motif RGD was fused to the PhoCl and was decorated on the hydrogel. After being exposed to light at 405 nm, the PhoCl was cleaved and the RGD motif was released, resulting in detachment of the binding cells. The regulatory effect of the light illumination showed a time-dependent and cell density-dependent manner. Furthermore, the elimination of RGD by patterned light exposure completely suspended the cell migration to the corresponding region, suggesting a controllable regulation of the cell migration direction.

The globus pallidus plays a pivotal role in the basal ganglia circuit. Parkinson's disease is characterized by degeneration of dopamine-producing cells in the substantia nigra, which leads to dopamine deficiency in the brain that subsequently manifests as various motor and non-motor symptoms. This review aims to summarize the involvement of the globus pallidus in both motor and non-motor manifestations of Parkinson's disease. The firing activities of parvalbumin neurons in the medial globus pallidus, including both the firing rate and pattern, exhibit strong correlations with the bradykinesia and rigidity associated with Parkinson's disease. Increased beta oscillations, which are highly correlated with bradykinesia and rigidity, are regulated by the lateral globus pallidus. Furthermore,bradykinesia and rigidity are strongly linked to the loss of dopaminergic projections within the cortical-basal ganglia-thalamocortical loop. Resting tremors are attributed to the transmission of pathological signals from the basal ganglia through the motor cortex to the cerebellum-ventral intermediate nucleus circuit. The cortico–striato–pallidal loop is responsible for mediating pallidi-associated sleep disorders. Medication and deep brain stimulation are the primary therapeutic strategies addressing the globus pallidus in Parkinson's disease. Medication is the primary treatment for motor symptoms in the early stages of Parkinson's disease, while deep brain stimulation has been clinically proven to be effective in alleviating symptoms in patients with advanced Parkinson's disease,particularly for the movement disorders caused by levodopa. Deep brain stimulation targeting the globus pallidus internus can improve motor function in patients with tremordominant and non-tremor-dominant Parkinson's disease, while deep brain stimulation targeting the globus pallidus externus can alter the temporal pattern of neural activity throughout the basal ganglia–thalamus network. Therefore, the comp
